    No and there are couple of reasons for that. First of all, playing GTO in 3+ way spots may lead to -EV decisions if someone deviates from GTO. Besides, in NL Holdem these spots don't come up very often and solving additional sizings and defense ranges for HU spots has more value.

  • What are “custom recalc settings” in the Hand’s window?
    It is a quick way of adding 1 (and only 1) sizing for current street and adding it to saved template for current spot. Imagine you are in the situation where you are IP on the Turn and face 10% pot-sized bet. But you only pre saved 50%,100%, 150% in recalculation settings for this spot. You can write 10 in the “OOP bet” on the Turn, run Recalculate and it will return a result for (10%, 50%, 100%, 150%) bets, effectively adding new sizing to the pre saved sizing’s template. CheckMath is all about speed of getting relevant results.
